LIFT-HANDLE FOR SASH ES.

-3PECIFICATION forming part of Letters Patent No. 331,336, dated December 1,1885. Application filed November 2, 1385. Serial X0. 181,702. (No model.)

' To aZZ whom it may concern.-

Be it known that I, WILLIAM F. SMITH, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented certain new and useful Improvements in Lift-Handles for Window-Sashes and like Purposes; and I do hereby declare that the following is a full, clear, and exact description of my invention, the accompanying drawings being therein referred to as forming a part of the specification.

My invention relates to lifting devices for window-sashes and other parts andstructures where a handle or projecting pieceis provided as a means for lifting the sash or part by hand; and my improvement consists in a novel construction and combination of face-plate and sliding finger plate, as hereinafter fully explained and pointed out, oroducing an improved lift that affords a handle or projecting finger-plate of a size to be readily seized for operating the window or part to belifted, and is thrown back into the plate to presentasubstantially flush front when not in use.

Referring to the drawings, Figure 1 is a view of the faceplate from the front. Fig. 2 shows the form ofthe finger-plate,or part that constitutes the handle, to be used with this faceplate. Figs. 3 and 4 are cross-sections taken through the parts when they are put together. These sections are taken in a perpendicular plane to one side of the center, and they represent the sliding plate in the two positions of extension and retraction from and within the face-plate. Fig. 5 is a top view of the faceplate. Figs. 6, 7, and 8 represent modifications employed in the production of sash-lifts from these two parts, as hereinafter explained. In these several views, Fig. 6 is a perspective view of the sash-lift shown in Fig. 7.

The face-plate A,Figs.1 and 5,has projecting cheek-plates A on the back to inclose and form a recess in which the finger-plate B is placed. The construction in this and in the other form shown in Fig. 8 requires these side pieces on the back of the face-p1ate;butin the modification seen in Figs. (Sand 7 they are not neces sary, and may be omitted. The face-plate is slotted at a, and through this opening the finger-plate B is drawn out and returned again, either by seizing the front end of the plate with the fingers, or, as is provided in the construction Figs. 3 and 4., by having a push piece or knob on the front of the face-plate, that is connected with the movable part B in such manner as to throw it out from the front when pressure is applied to the push-piece. The plate B is made of curved shape by preference, and is confined by a hinged or pivoted armor extension, as in Figs. 3, 4., and 7, so that it moves easily in a curved path, according to its own curvature.

To prevent the possibility of slipping back into the slot under the upward pressure or force exerted in lifting the sash, a stop-shoulder, b, is formed along the top of the plate to take under the top edge of the slot a, as shown in Fig. 3, sufficient vertical play of the sliding piece being provided to bring this shoulder in front of the edge of the slot, and to throw it down again clear of the same when the plate is to be returned.

In the construction Figs. 1 to 5 I form a hook, B, on the bottom ofthe arm or member B that carries the finger-plate, and carry the ends of this hook out through a small slot, a

near the lower edge of the faceplate, in such manner that when the plate B is thrown in flush there is' suitable projection of the hook end to serve for pressing the same back and turning the plate on its center of movement. This center consists of a small rib, a on the back of the faceplate, just over the top of the slot a. The hook is kept against this rib by the pin (Z. On the inner faces of the plates A are lugs e e, that form stops for the plate B. Theseand the hook are not in the construction of this lift, which is shown in Figs. 7 and 8, as the front edge of the plate B is pro vided with a lip, 21*, that not only serves to keep the plate in place, but also furnishes sufficient amount of projection to be caughtby the finger nails or tips for the purpose of drawing out the plate. In this form of the lift the pivot is produced of a hook, B on the bottom ofthe plate B, and a pin, d*, fixed in lugs a cast on the back of the plate A.

In that construction shown in Fig. 8 the pivot is dispensed with and two curved lugs, e are formed on the sides of the plates A ,a-s guides for the curved plate B.

In all these forms the face-plate A and curved ICO sliding finger plate constitute the essential parts or members of an improved flush lift, as above described.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. The improved liftinghandle consisting of a slotted'faceplate, A, and the sliding plate B, working through the slot of the face-plate, and adapted to be drawn out from the front thereof for a finger piece or handle, and to be returned again within the face-plate to present a flush surface, the back of the sliding plate having a stop to prevent it from being entirely withdrawn from the slot, substantially as shown and described.

2. The combination of the face-plate A and the sliding finger-plate or handle B, confined sliding finger-plate B, pivoted to the back of 25 the faceplate and working through a slot, as a, and the projection on the lower end of the plate, at or near the line of the pivot, working through a slot in the plate A, as a means for throwing out the plate B, substantially as dec scribed, for the purpose set forth.
